JOHN IIAGGERTY, OF NEW YORK, N. Y.

FURNACE.

SPECIFICATION forming part of Letters Patent No. 465,646, dated December22, 1891.

Application filed November 12, 1890. Serial No. 371,227. (No model.)

To ctZZ whom it may concern;

Be it known that 1,.TOHN HAGGERTY, a citizen of the United States, and aresident of New York, in the county and State of New York, have inventeda certain new and useful Improvement in Furnaces, of which the followingis a specification.

My invention relates to plumbers furnaces, and has for its object theprovision of a device simple in construction, cheap in manufacture, andefficient in practical use.

To attain the desired end my invention consists in the construction andarrangement of parts hereinafter first fully described, and then pointedout in the claims.

In the drawings which form a part of this specification, Figure 1represents a vertical central section of an article constructedaccording to my invention,and Fig. 2 is a trans verse section on theline so as, Fig. 1.

Like letters of reference wherever they occur indicate correspondingparts in both figures.

Referring again to the drawings, A represents the furnace proper,ordinarily constructed of heavy sheet metal and provided withmalleabledron legs and grate and also with a suitable handle, and beingof about the same size as the regular furnace for plumbers and othersuse. The furnace A is also provided with, preferably, twointeriorly-projecting vertical bearings a, located opposite each otherat or near the top of the same, at

the lower portion of which bearings (t are placed the projections orstops to.

The pot B, which contains the metal to be melted, is furnished with ahandle of ordinary description, and is also provided with lateralvertically-grooved lugs or ears I), adapted and arranged to engage withand slide down upon the bearings a, the grooves being deeper at thebottom of the lugs than at the top, thus forming offsets or shelves Z),which serve when the pot B has completed its downward course to restagainst and to be supported by the stops to of the bearings a. The size,location, andarrangement of the lugs 19, offsets b, bearings a, andstops a are ordinarily so determined with relation to the grate C thatwhen the pot B is supported by the stops c the bottom of the sameordinarily rests about two inches above the grate,

there being usually a space of about two inches also left between theexterior of the pot and the inner face of the shell of the inclosingfurnace.

with charcoal and the pot containing the metal to be melted placed uponthe same, the lugs Z) engaging with thebearings a. As the charcoal burnsaway, the pot slides down, following the fire, as represented in Fig.1,until it rests upon the stops at. The annular space between the pot Band furnace A affords means for feeding the latter by the tender, whocan pack charcoal under and around the pot.

Bythe use of my improved furnace all danger of spilling the molten metalis obviated, inasmuch as the pot cannot be overturned. It can, however,be removed without trouble at any time when required for use andafterward readily replaced.

As it is evident that many slight changes in the construction andrelative arrangement of parts might be resorted to without departingfrom the spirit and scope of my invention,l would have it understoodthat I do not restrict myself to thepart-icular constructionandarrangcmentof parts shown and described, but that I reserve the rightto make such changes, and that hat I claim as new, and desire to secureby Letters Patent, is-

1. The combination,with a furnace provided with lateral bearingscarrying a stop at their lower extremities, of a pot provided with lug'sadapted and arranged to engage with the said furnace-bearings, wherebythe pot may descend vertically within the furnace and be sustainedwithin the same at a fixed point above the grate, substantially asdescribed.

2. The combination,with a furnace provided with lateral bearings andcharged at the lower portion of the same with burning charcoal, of aninterior pot supported by the charcoal and provided with lugs adaptedand arranged to engage with the furnace-bearings, whereby the pot maydescend vertically within the furnace and slide down upon the saidbearings resting upon and following the fire, substantially asdescribed.

3. The combination,with a furnace provided with lateral bearingsextending inwardly, of

In practical operation the furnace is charged a pot provided with lugsprojecting from the I do hereby Sign the san1e,in the city of New sameand adapted and arranged to engage York, conntyandStateof NewYork, this24th 10 with the said furnace-bearings, whereby the day of October, A.D. 1890.
